Answer:
Each angle within that right angle measure 45 degrees.
Step-by-step explanation:
Given:
The two pieces of furniture forms Right angle
The Right angle is bisected by another bar
To Find:
what would each angle measure within that right angle = ?
Solution:
The Two furniture are attached such that the ange betwwn them is right angle.
The right angle measures 90 degrees
Then an another bar bisects this right angle.
The word bisects means divided into two equal halves
so bisecting the right angle means, bisecting 90 degrees
=>
=>45 degrees
Answer:
y =
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis.
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
Here the line passes through (0, ) with y- coordinate
, thus
y = ← equation of line
Answer:
The value of the test statistic = 2.58
Test statistic Z = - 4.805
|Z| = 4.805 > 2.58
Null hypothesis is rejected The value of the test statistic = 2.58
There is significant difference between in the mean number of times men and women send a Twitter message in a day
Step-by-step explanation:
Step(i):-
Sample size of men n₁ = 25
mean of the first sample x₁⁻ = 20
Standard deviation of the first sample σ₁ = 5
Sample size of women n₂ = 30
mean of the second sample x₂⁻ = 30
Standard deviation of the first sample σ₂ = 10
Level of significance ∝= 0.01
<u>Step(ii)</u>:-
Null Hypothesis : H₀: There is no significant difference between in the mean number of times men and women send a Twitter message in a day
Alternative Hypothesis :H₁:There is significant difference between in the mean number of times men and women send a Twitter message in a day
Test statistic
Z =
The value of the test statistic = 2.58 C
|Z| = 4.805 > 2.58
Null hypothesis is rejected The value of the test statistic = 2.58
<u>Conclusion:</u>-
There is significant difference between in the mean number of times men and women send a Twitter message in a day
